Abstract
A passive roof vent is provided with a planar upper surface which includes channels on the sides and bottom of the panel to hold shingles. The side channels are stepped to permit two layers of shingles to be inserted over the top surface and provide a shingled appearance. This provides an aesthetically appealing roof vent which has an upper surface which blends in with a shingled roof.
